Renewable energy is driving profound changes in cities. It’s happening much more quickly than was expected even five years ago. Responding to climate change, networks of decision-makers, such as the C40 collective of major cities, have begun adopting strategies to promote the uptake of renewable e...

The planets closer to the Sun than the Earth are indeed hotter than the Earth is. But that still doesn’t make them hot enough to melt the rocks that they are made from!

Where are we within our galaxy? How did our galaxy form? How did it evolve over the aeons?
Astronomers have been asking these questions for the past century, and have recently begun discerni...

Stars are immense, but the space between them is truly phenomenal. chefranden
Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

Space probably does go on forever, but the truth is we don’t know. Not yet anyway. That’s what makes this a great question, because science is all about finding answers to things we don’t know yet.
